RESUMO
Objective To observe the clinical efficacy of Weixuening granule combined with prednisone for treatment of patients with primary immune thrombocytopenia (ITP) and its impact on platelet-associated antibodies(PAIgG, PAIgM, PAIgA). Methods Sixty patients with ITP were randomly divided into a observation group (30 cases, Weixuening granule combined with prednisone) and a control group (30 cases, prednisone therapy alone), 3 months constituting a therapeutic course. The clinical effects, platelet count (PLT) and PAIgG, PAIgM, PAIgA of two groups were observed after two courses of treatment. The time of withdrawing prednisone, relapse rate in 1 year and adverse reactions were also monitored. Results The total effective rate of the observation group was higher than that of the control group [90.00%(27/30) vs. 73.33%(22/30), P0.05). Conclusions The combined use of Weixuening granule and prednisone for treatment of patients with primary ITP is more effective than administration of prednisone alone;the adverse reactions are less in combined therapy group. Possibly, the better therapeutic effect of combined therapy is related to the decrease of platelet-associated antibodies and increase of the platelet generation.
RESUMO
Objective To establish a method for determination of polysaccharides in Weixuening Granule, which can be used for quality control of the preparation. Methods Polysaccharides was determined by improved differential phenol-sulfuric method with glucose as reference, and the color conditions were optimized at the wavelength of 487 nm, with the concentration of phenol and sulfuric acid, and reaction time as investigated factors. Results The best color conditions of polysaccharides were 0.04 g/mL phenol 1 mL, 87.5% sulfuric acid 5 mL, and reaction time of 15 min. Glucose had a good linear relationship with absorbanceΔA at the range of 15.3-306.0μg, r=0.999 7. The average recovery was 103.5%, and RSD was 2.9%. The average content of polysaccharides in Weixuening Granule was 27.04%and RSD was 1.1%. Conclusion The method is simple, accurate, stable and reliable, and can be used to determine the content of polysaccharides in Weixuening Granule.
